I found this on wiki:
Cluster beacons

A group of radio beacons with single-letter identifiers ("C", "D", "M", "S", "P", "A", "M" and "K") have been regularly reported in
small spectrum segments centered around 3594, 4558, 5154, 7039, 8495, 10872, 13528, 16332 and 20048 kHz. The term "cluster beacons"
is frequently used for them, as these beacons transmit in parallel on frequencies only 0.1 kHz apart. These beacons transmit only
their single-letter identifier in standard CW (A1A) using morse code.

The following callsigns and frequencies of cluster beacons have been reported recently in Numbers&Oddities newsletter, Utility DX
Forum and ENIGMA-2000:
ID letter 	Channel 	Frequencies (kHz)
L (21) 	-0.8 	7038.2, 7041.8(23), 8494.2, 8497.9
D 	-0.3 	3593.7, 4557.7, 5153.7, 7038.7, 8493.7, 10871.7, 13527.7, 16331.7, 20047.7
P 	-0.2 	3593.8, 4557.8, 5153.8, 7038.8, 8494.8, 10871.8, 10872.8 (21), 13527.8,
16331.8, 20047.8
S 	-0.1 	3593.9, 4557.9, 5153.9, 7038.9, 8494.9, 10871.9, 13527.9, 16331.9, 20047.9
C 	0.0 	3594.0, 4558.0, 5154.0, 7039.0, 8495.0, 10872.0, 13528.0, 16332.0, 20048.0
A 	+0.1 	3594.1, 4558.1, 5154.1, 7039.1, 8495.1, 10872.1 13528.1 16332.1 (10)
F 	+0.2 	7039.2, 8495.2, 10872.2, 13528.2, 16332.2
K 	+0.3 	4558.3, 5154.3, 7039.3, 8495.3, 10872.3, 16332.3
M 	+0.4 	5154.4, 7039.4, 8495.4, 10872.4, 13528.4, 16332.4

Occasionally some cluster beacons (especially "F" and "M") have been reported transmitting on frequencies different from their
regular channel for short periods.
